Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed February 6, 1917. Serial No. 146,977.

To all whom it may concern:

' Be it known that I, HERMAN NIELSEN, Ingemansvej No. 9, Copenhagen, Denmark, have invented certain new and useful Improvements in Outflow-Regulators; and I do hereby declare the following to be a full,

. clear, and exact description of the invention,

such as will enable others skilled in the art to which it-appertains to make and use the same, reference being had to the accompany- .ing drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to apparatus for regulating the outflow of a fluid from a container, the same being especially designed for'use in connection with oil cups or lubritially the same, notwithstanding variations in the level of the oil in the container. A further object of the invention is to provide means for adjusting the device whereby the speed or volume of outflow may be increased or decreased and whereby variations in the I density of the liquid whose flow is Icontrolled, may be compensated for.

Other objects of he invention will hereinafter'appear and thenovel features thereof will be set forth in the claims.

In the drawing forming part of the speci-' ficationz' Figure 1 is a sectional elevation of an oil 7 cup'or lubricator embodying my invention;

Fig.2 is an elevation of a modified form of buoyant member; and

Fig. 3 is a'detail View.

'Th'e-oil'cup orcontamerl may be of any usual or preferred construction, Ais shown,

, vided with a discharge or outflow opening 3.

it has extending centrally through it averti- I cally disposed tube 2 which projects down below the lower end-of'the cup or container 1 where it is contracted-in shape and pro- The said tube is alsojprovided at' points slightly above the bottom ofthe cup or corn was rwith la ports era-sages screw threads 5.

18 having a The said tube extends upwardly above the top of the container 1 and is provided with Screwed upon the upper projecting end ofthe tube 2 is a cap 6 hav- -mg a central axial opening therein, and

upon saidcap is mounted an inverted U- shaped frame orsupport 7. Located within the tube 2 is a buoyant member or float 8, the same being shown as cylindrical in form. This buoyant member is preferably made of metal orother material of greater specific gravity than the oil or other liquid 9 in the container 1. The lower end of the buoyant member 8 has a contracted neck 10 forming a shoulder '11 and carrying a downwardly opening valve 12 which controls the, flow of oil or other fluid through the discharge opening3. The shoulder 11 is adapted to cooperate with'a seat 13 in the contracted portion of the tube 2 for the purpose of cuttingofl' entirely the flow of liquid through the opening 3 when the device is not in use. The buoyant member 8 is supported by or suspended from a coil spring llwhich is vsecured to the upper end of said buoyant member, and is also se- Qcured to a cylindrical block 15 which extends through the axial opening in the cap 6.

The said, block is capable of being turned and moved longitudinally of said opening.

It is normally supported from the inverted U-shaped frame or bracket 7 upon-two studs 16 which are screwed into and extend inwardly from the vertical members of the frame 7 and fit into L-shap'ed slots 17 in the upper end, of the block 15. In Fig. 1 the studs 16 are shown aslocated in the horizontal portions of the slots 17 and the buoyant member 8 is supported with the shoulder 1 11 thereon elevated away from the seat 13 surrounding, the discharge opening '3. By turningthe block 15 until the studs 16 come opposite the vertical portions of the slots 17 the said block, and with it the buoyant 5 member 8, may be lowered until the shoulder .11 is' brought into engagementwith the seat 13 and. the outflow opening 3 completely closed. This "operation will be effected when the lubricator 1 is notin use and it is desired to prevent any flow of oil therefrom.

Extending vertically 'through a central opening in the block 15, is a rod or spmdle knob or handle 19' at its upper end 'by meansofwhich it may be turned 1 and. having ascrew 20 upon its "lower end which fits'within the coils ofthe spring 142 The said screw 20 has been shown as a block or enlargement on the lower end of the rod 18 having an external outwardly extending 1 spiral rib 21 thereon. This rib hasbeen shown as fitting between two adjacent coils of the spring 14:. The purpose of the screw 20 1s to adjust-the spring 1 4:- so: as to vary theelas-- ticity thereof or ratheritheextentof effectiveness of said spring on thebuoyant memiber8. It willbe understood that theonly z portion :of the spring 14: which is leffective upon the buoyant member 8 :is that ,below .the screw 20., Bylturningsaid screw downwardly,-ithe portion of thespring .141, .whlch :is effective upon-the buoyant member 8 is reduced, whereas by turnmg the screw 20 upwardly the efiectiveportion ofthe spring 14 is increased.

lllhebuoyant .member .8 being submerged inithe oil onother liquid in the container .1,

is partially sustained .by such. oil or other liquid and partially by thefspringxl l. It can readilyibe understood thatzif a-buoyant member were employed which was sustained wholly by the liquid- .in the container ,and

Which also ihad the.,o utflow valve '12 connected to it, such, buoyant member would .fall with theliquidinthe container as its level lowered, but-the ;.movement=- of the buoyant member and consequently of the statiopressure. It is necessary, in-other words, in order tohbring about this result, that the downward movement of-the buoyant .member carrying the ,valve controlling the outflow openingbe less than the-downward movement in theilevel of the liquid.

It is toaccoinplish this. result that I provide for;the support ofthe buoyant member 8 on gthe spring .14. -,For .while the buoyant .ImembenS oarrying thevalve 12 will drop 1 with-La loweringofpthe levelwoithediquid 9, iduefto the fact that .it a is partially sustained by the said liquid, its downward movement is resisted byethespring le so that it .willnot tall ,to as; great an; extent as the level of the liquid, butswill fall just, so much; asto, open -thevalve 12 to just -suchanpextent as to compensate ;for the-decrease in the/hydrostatiqpressure I and bring-,about an. equaliza- {tion in the: outflow regardle ss of changes in level or hydrostaticflpressure,in ,thel'liquid.

respect to the outflowopening'3 may be adjusted by turning the cap 6 either up or down onthe upper end of the tube 2. This adjustment, as well as the adjustment of the spring '14, enables me to adapt the device for from the same.

The cylindrical formof the buoyant member Sisparticularly welladapted for use in connection with oilcups orvlubricat ors for machinery, but with other fluids than oil or .wherefgreater outflow speeds are required, it maybe desirableto change the shape of the buoyant member. shape whichimay be made,'is illustrated in One variation 'in Fig. I2 of the drawing. in which 8? indicates .the buoyant. member and 12? the valveat the lower end thereof.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
